For guys it’s usually where the sun don’t shine- arm pits and leg pits and under the scrotum (jock itch). When I have gotten yeast infections due to antibiotics it’s always been in these areas. You can knock it out by using Zeabsorb antifungal powder and by tanning naked, for just 5 minutes. Fungi don’t like sunshine which is why you only see mold develop in moist and dark places. I also use a blow dryer after showering to keep arm and leg pits dry. Never put ointments or cream on a yeast infection on your skin because they all have water - use powder, keep area dry and exposed to intense light. I am a veteran of major yeast wars and this is how you fight them off.
